Rudder Pedal Assemblies

Name: Rudder Pedal Systems & Aircraft Direction Control Units – Frigate
Price: 249.00 USD
Availability: InStock
Rating: 5 (837 reviews)

Rudder pedal assemblies endure localized mechanical stresses from pilot input, braking forces, and vibration-induced fatigue. Their structural design—including pedal arms, brackets, and actuator linkages—is guided by finite element simulations to ensure balanced stress distribution across all load paths.

Material Specification

Aluminum 6061-T6 (Pedals), Stainless Steel 17-4PH (Linkage), Carbon Fiber (Optional)

Pedal Travel Range

±100–150mm (Full Deflection), Adjustable Stops (±10%)

Mechanical Advantage

4:1 to 6:1 Ratio, Cable/Pushrod Interface Optimized for 25–50N Pilot Input

Brake Mechanism Type

Dual Differential Braking, Hydraulic (3000 psi) or Electric (Fly-by-Wire)

Adjustability

Fore/Aft – 150–250mm (Pilot CG), Pedal Angle – ±15°, One-Hand Locking

Product Description

Key design features such as reinforcement ribs, optimized fillet radii, and failure mode analysis are integrated early in development. This ensures high resistance to plastic deformation and fracture, even under peak load scenarios like dual-pilot asymmetric input events.

Load Capacity

Pilot Input – 500N Max, Structural – 1500N Ultimate (FAR 25.561)

Feel System Interface

Spring-Centering (10–20N/mm), Friction Damper (Adjustable 5–15N)

Life Cycle

100,000+ Cycles (No Wear), Lubrication-Free Bushings

Dimensional Tolerances

Pivot Bore – ±0.01mm, Pedal Symmetry – ±0.5mm, Linkage Parallelism – ≤0.1°

Certification Standards

Pivot Bore – ±0.01mm, Pedal Symmetry – ±0.5mm, Linkage Parallelism – ≤0.1°

Technical Advantages

Any mechanical compliance or backlash within the rudder pedal linkages directly translates to degraded yaw control accuracy. This is mitigated by employing preloaded spherical bearings, splined torque tube couplings, and axial thrust bushings with micron-level fit tolerances. Pedal displacement produces an immediate and linear output response at the rudder control actuator, with no perceptible lag, ensuring precise control authority in both manual and fly-by-wire configurations.

Aircraft platforms with dual cockpit control positions demand symmetrical force and displacement fidelity across both pedal sets. The mechanical coupling uses torsionally rigid torque tubes with calibrated torsional stiffness coefficients and aligned bearing housings to minimize angular phase lag. Load-sharing is verified through differential force mapping during bench testing, ensuring synchronized actuation even under offset input forces and cable routing asymmetries.

Industry Applications

Commercial Aircraft Cockpit Control Systems

Transmits pilot foot input to rudder actuators, ensuring accurate yaw control in full-authority and hybrid fly-by-wire architectures.

Military Fighter Jet Flight Controls

Interfaces with digital flight computers and mechanical linkages to provide high-frequency rudder feedback during high-g maneuvers and evasive operations.

Rotorcraft Anti-Torque Pedal Systems

Controls tail rotor pitch via hydraulic or electronic actuators, stabilizing yaw movement during hover, climb, and autorotation phases.

Flight Training Simulators

Provides mechanical realism and force feedback simulation, replicating real-world rudder behavior for pilot training and procedural instruction programs.

Business Jet Modular Avionics Integration

Integrates within compact cockpit layouts with adjustable travel range, linking rudder pedal displacement to digital avionics control loops.

Unmanned Aerial Vehicle Ground Stations

Used in pilot-in-the-loop setups to translate operator foot motion into yaw control commands for large-format remotely piloted aircraft.

Adjustable Ergonomics with Mechanical Precision

Adjustment mechanisms integrated into the pedal base accommodate varying anthropometric profiles of flight crew members while maintaining fixed pivot axis geometry. Travel limiters and locking sliders are mechanically interlocked to prevent mid-flight reconfiguration.

The rudder pedal assemblies is designed for modular integration into a wide range of cockpit floorpan geometries and flight control systems. Mounting interfaces conform to standard aerospace hole patterns, while the mechanical stroke and linkage geometry are tunable to support both conventional hydraulic rudder control and electro-mechanical fly-by-wire architectures.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure tight tolerances during rudder pedal assemblies manufacturing?

Frigate uses precision CNC machining with dimensional control up to ±0.01 mm on all mating surfaces and bore alignments. Coordinate Measuring Machines (CMM) are used during in-process inspection to verify geometric tolerances. All critical features undergo GD&T validation per AS9102 standards. This ensures consistent pedal displacement, load transmission, and sensor alignment.

Can Frigate integrate flight control sensors directly into the pedal assembly?

Yes, Frigate offers factory-installed mounts for LVDT, RVDT, or potentiometers based on system requirements. Sensor alignment is maintained with reference to the pedal’s neutral axis using machined reference flats. Wiring harness routing and EMI shielding are designed per DO-160 standards. This enables seamless integration into digital flight control systems.

What surface treatments does Frigate use to protect assemblies from corrosion?

Frigate applies MIL-A-8625 anodizing for aluminum parts and MIL-DTL-5541 alodine conversion coatings for mixed-metal interfaces. Titanium and stainless-steel components use passivation or dry film lubricants where applicable. Fasteners are selected to avoid galvanic corrosion using proper isolation techniques. Coatings are tested for salt spray resistance and fluid compatibility.

How does Frigate support modular cockpit integration across different aircraft platforms?

Frigate designs rudder pedal assemblies with standardized mounting patterns and configurable linkage geometry. Each unit can be adapted to various pedal stroke lengths, travel limits, and interface requirements. Optional features like toe-brake linkages and adjustable pedal positions are available without altering core structure. This reduces design rework and accelerates system-level integration.

What lifecycle testing does Frigate perform on rudder pedal assemblies?

Frigate conducts full-cycle fatigue testing exceeding 50,000 actuation cycles under operational loads. Vibration, thermal cycling, and salt-fog exposure tests are performed to validate environmental durability. Functional testing includes backlash measurement, force-displacement mapping, and synchronization of dual-station units. All tests are documented with traceable data for aerospace compliance.
